TOY PINWHEEL.

To all 107mm it may concern:

Be it known that I, TILGHMAN. GRAHAM, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Toy Pinwheels, of which the following is a specification.

My invention enables me to make cheap, strong, durable, handsome, pin-wheels, by the duplicate part system, out of very light card board and paper and to pack them in small compass, for shipment.

In the accompanying drawings, Figure 1 is a side elevation; Fig. 2 is aperspective of a detail; Fig. 3 a section on line 11 of Fig. 1: Fig. 4 a plan of Fig. 1; Fig. 5 a section View on line at'-t of Fig. a Fig. 6 a reduced section on line 33 of Fig. 1; and, Fig. 7 a plan illustrating another method of forming the rotating members.

In the preferred form of my invention, 1 punch a wheel blank 1 with its rim 1-1, spokes 2, 3, 4: and 5, and hub 6, out of cardboard, helically attach vanes or bannerets, '7, 8, 9 and 10 to said spokes so as to form a windwheel, paste to the face of the hub (3 a strut 15, which is preferably a wooden button with a flat base and av spherical face, and truss the wheel with diametrical or radial ties, 13. past-ed to the outer parts of the wheel-blank 1, preferably to its rim, 14:, and strained over the strut 15.

Preferably the ties are an integral cross, stamped of thin paper, with arms extending from a hub 16; but narrow, crossed strips will be equally effective but more costly in application.

The pin wheel thus formed can be pinned directly to a stick or handle 18; but to en able me to pack and ship them cheaply, I prefer to hinge the handle and to this end I provide a sprin clip or clevis 19, preferably stamped of thin spring metal, with a head 22 perforated with a pinhole 23 and cylindrical-segmental arms 20 and 21, adapted to grasp the end of the stick 1S and to be hinged to it The pin, 17, on which the wheel rotates, extends through the hole 23 in the clevis head 22 and the wheel hub 6, strut, 15, tie-hub 16 and an axial ornament 11 (illustrated as a hat) and holds all the parts together, its ends being upset or otherwise shouldered to that end. The wheel is hinged to the stick 18 by a pin 2e; loosely riveted through it and the clip arms 20, 21

with enough play to enable the user to swing the wheel parallel with the stick (dotted lines, Fig. l) Clip-arms 20 and 21 normally clasp the end of the stick and hold the wheel perpendicular thereto.

A cheaper mode of construction is illustrated inFigs. (5 and 7, in which I omit the hub 6 and arms 2, 3, 1 and 5 of the wheel blank, thus constituting it a mere ring punch slots in a cardboard blank to separate the adjacent vanes 7, 8, 9 and 10, leaving them connected with the central hub by rudimentary spokes 25, 2G, 27, 2S and notch the outer sides of the vanes to form tabs 29, 30, 31, 32, by which it is pivoted to the wheel-rim 33, the spokes 2, 3, 4:, 5, being thus replaced by the anterior limbs of the vanes; and truss and assemble the wheel thus formed with the strut, ties, clevis, pin and stick, as in the previously described mode.

As illustrated in Figs. 1 and 6, the vanes are bent substantially in helical or screwform so that when the wheel is held head to the wind it will be revolved; and the tensile strength of the ties 13, and the compressive strength of the wheel blank and strut 13, all of which as assembled constitute a perfect truss, enable the wheel to sustain great windpressure without injury.

It is obvious to those familiar with framing or trussing similar bodies that in its normal use, with full pressure, the ties 13 are in tension and the spokes in compression and the rim 1% in compression and bending; that under reverse pressure the ties 13 are in compression and the spokes in'tension; that either the spokes or ties must be elements (preferably radial) of the surface of a cone or conoid; and that they can be uneven in number, offset, and radial without departing from the spirit of my invention because their hubs G and 16 will receive and properly transmit the stresses and strains generated in the spokes or ties; also, that I may make the back conoidal instead of the face as illustrated, or both faces conical; and also, may make the radial truss-members curved in elevation.

The essence of my invention is, to make a trussed paper or card-board pinwheel coinprising punched tie and compression members and an axial strut, all united in conical or conoidal form.

I claim 1. A trussed paper pinwheel comprising a ring, compression members and tension members respectively united adjacent to the axis and to said ring, an axial strut distending said compression'and tension members, substantially helically arranged vanes and an axial pin. 7

2. A trussed paper pin Wheel comprising a ring, a unital face member slotted to form substantially helical vanes and truss-members of one face of said pin Wheel, oppositeface truss members united With one another, said ring, un'ital face members and opposite face members being united, an axial strut distending said opposite face members, and an axial pin.

3. A trussed paper pinwheel comprising a ring, compression members and tension members respectively united adjacent to the axis and to said ring, an axial strut distending said compression and tension members,

substantially helically arranged vanes, an axial pin, a clevis to which said pin is axially fastened and secures the Wheel, and a handle hinged in the clevis.

4. A t-russed paper pinwheel comprising a ring, compression members and tension members respectively united adjacent to the axis and to said ring, an axial strut distending said compression and tension members, substantially helically arranged vanes, an axial pin, a clevis to Which said pin is axially fastened and secures the Wheel, cylindro-segmental arms on said clevis, adapted to clasp the end of a handle, and a handle hinged in said clevis.
